LUBBIGATING DEVICE.

T0 a?? Qczom t may concern.'

Be it known that l, FRANK P. Bti-SIEL, citizen of the United States, andresident of Somerville, county of h/iliddlesex, lr'iassachusetts, haveinvented certain new and useful improvements in Lubricating Devices, ofwhich the following is a specification.

rlhis invention relates to lubricating devices, and is particularlyintended for the lubrication of guide rails for elevators,counterweights and other apparatus in which guide rails are employed.

lt is the object of the invention to provide a simple and convenientdevice of this class which shall maintain perfect lubrication of therail at all times without wasting the lubricant and without scoring orunevenly wearing the rail or track against which it acts.

Generally speaking, the invention comprises a carrier in the form of ashoe, which is so attached to the traveling or moving member running onthe guide rail, such as an elevator car, to accommodate itself perfectlyto the swaying, tilting and lateral movement of the car, withoutdisturbing the equal distribution of pressure and the proper applicationof the lubricant.

To this end the invention comprises a bracket adapted to be detachablysecured to the car or other moving part, upon which is mounted a shoehaving engagement with the guide rail to be lubricated, said shoe beingnormally pressed with a yielding pressure against the guide rail whileremaining free to tip laterally or longitudinally as well as in a planeparallel to the guide rail.

ln the accompanying drawings I have illustrated two simple forms ofembodying my aforesaid invention, in whichm Figure l is a side elevationof the device attached to the counterweight of an elevator; Fig. 2 is afront elevation looking toward the guide rail; Fig. 3 is a horizontalcentral section on the line 3 3 of Fig. l; and Figs. et. .3, and 6 aresimilar views showing a modified construct-ion and arrangement.embodying the same principle.

According to the form of my invention embodied in Fig. l, l provide anangle Specification of Letters Patent.

bracket a whose horizontal arm is slotted to receive the fastening bolta, by which it is attached to the counterweight slide, so that it may beadjustable toward or away from the guide rail m. The vertical arm a2 ofthe bracket a is provided with horizontal slots as shown at a3, toreceive clamping screws which detachably hold the spring arm L to thebracket while permitting the adjustment of the spring arm laterallythereon.

rlhe upper end of the spring arm b is bent to form a loop or elongatedeye b2, through which is passed a pivot bolt c carried in lugs or earsc2 projecting from the guide shoe c. lt will be observed that the springarm b is made substantially narrower than the supporting portion of thebolt c, said bolt. being as shown in dotted lines much smaller than thebore of the eye b2, so as to permit the shoe to have a considerable playin all directions. In this way the shoe can freely accommodate itself tothe guide rail in spite of the lateral movement of the counterweights orcar by which the guide is supported. At the same time the parts are soproportioned and adjusted that the arm Z1 normally exerts a substantialpressure, which is transmitted through the pivot bolt c to the shoe tokeep the interior of the shoe in close contactI with the guide rail. Thepivotal joint between the spring arm and the lubricating shoe c permitsthe shoe to always remain in parallelism with the rail, in spite of anytipping or tilting of the car away from the rail or toward it and thusprevents the scoring or roughening of the rail itself, which mightresult from such movements of the car, if the joint were a rigid one.

rEhe lubricant is preferably in the form of a solid candle cl ofsuitable lubricating material, which is placed in a tubular holder dwhich is inserted by a screw threaded connection into the end of theaperture formed at c3 in the lubricating shoe c. This aperture in thelubricating shoe at the entering end is slightly larger than the widthof the rail, so that the lubricant may spread over the lateral faces ofthe guide rail.
